Hello, All. I stopped using a laptop for a few years. I starting using it again and updated Xojo to 2024 r2.1. When I load Xojo I receive an error message that says it find something in the \AppData\Local\Temp\XojoIDEPlugins\ folder.
Thanks to both of you for your responses. I suspected the Valentina plugin. I have had some problems with the installation elsewhere too. I removed only it first and the error message did not come up after I relaunched Xojo.
